Article Synopsis
- - The study examined the effects of natural dimethyl sulfide (DMS) and ship emissions on marine air quality and particulate matter (PM) around South Korea, using modeling from field data collected in 2017 and 2018.
- - DMS oxidation increased the levels of sulfur dioxide and sulfate in the atmosphere, while slightly decreasing nitrate levels, indicating its role in marine air chemistry.
- - Ship emissions significantly raised concentrations of sulfur oxides, nitrogen oxides, and ammonia, and were found to be a major contributor to non-sea-salt sulfur in PM, highlighting the impact of maritime activities on air quality.
The Amazon is a significant source of atmospheric methane, but little is known about the source response to increasing drought severity and frequency. We investigated satellite observations of atmospheric column-averaged methane for the 2010 drought and subsequent 2011 wet year in the Amazon using an atmospheric inversion scheme. Our analysis indicates an increase in atmospheric methane over the southern Amazon region during the drought, representing an increase in annual emissions relative to the wet year.
